Patented Aug. 4, 1931 UNITED STATES RAY C. WORSWICK, OF ROSWELL, NEW MEXICO DRAIN FILTER Application filed March 18, 1931.

This invention relates to drains and more particularly to an apparatus for separating and removing the solid matter from the water used to clean utensils before said water enters the sewer.

The principal object of the invention is to provide an apparatus for collecting all the solid matter or residue formed by washing dishes, glasses, and other utensils and thus prevent the plumbing system from being clogged up.

Another object of the invention is to provide a device of this kind having an outer casing, a removable inner collecting basin, and straining means in said basin for allowing the water to drain off.

Still another object of the invention is to provide a double set of strainers in the collecting basin, one for straining the coarse waste or residue and the other the fine waste or residue.

Other objects will appear as the disclosure progresses. The drawings are intended to merely indicate a possible embodiment of the invention. It is obvious that the actual needs of manufacture may necessitate certain mechanical changes. It is therefore not intended to limit the invention to the embod' iment illustrated but rather to define such limits in the appended claims.

For a more general understanding of the invention attention is called to the drawings. In these drawings like reference characters denote like parts throughout the specification.

Figure 1 is a cross sectional view of the device shown attached to a kitchen sink. 7 Figure 2 is a slightl modified form of the invention shown attached to a soda fountain 4A) drain apparatus.

Figure 3 is a section on line 38 of Figure 1.

Figure 4 is a section on line l4 of Figure 1.

Figure 5 is a side view of the handle used to remove the basin.

Figure 6 is a front view thereof.

Figure 7 is a cross sectional view of a mod ified form of the strainer. Figure 8 is a bottom view thereof.

Serial No. 523,611.

Figure 9 is an enlarged view of the auxil iary strainer.

Referring now to the drawings in detail, numeral 1 designates a standard kitchen sink, 2 the drain, the subject of the invention, and 3 the plumbing line leading to the sewer. The drain comprises an outer cylindrici casing having a flange 5 at the upper end which is attached to the bottom of the sink by the bolts 6. The lower portion 7 of the casing tapers to a comparatively narrow pipe 8 which leads into the plumbing line 3.

Placed in the outer casing is a removable basin 9 supported by the flange 10 which rests on the flange 5 of the outer casing. The basin is cylindrical in shape with an open bottom and is provided with two pairs of longitudinally formed grooves 11 and 12. The grooves 12 ext nd to the bottom of the basin and support a strainer of comparatively fine mesh 13 by the pair of ears 14 which fit in the said grooves as clearly seen in Figure 1. The grooves 11 do not extend to the bottom of the basin but end a short distance upwardly and support a comparatively coarse strainer 15 by the ears 16 fitting into the grooves 12 as noted in Figure 4. Near the interior end of tapered portion 7 of the outer casing is placed an auxiliar strain 17 of very fine mesh. This strainer has an upwardly bent flange having a taper which matches with the taper of the casing. Above the strainer is an eye 18 for being engaged with a suitable tool when it is desired to remove the strainer for cleaning purposes.

Fastened within one of the grooves 12 by the rivet 19 is a handle 20 having a bent portion 21 at the upper end. The handle is made from spring steel and is normally in the position as shown in Figure 5, so it can readily be hooked when is desired to lift the basin out of the outer casing when cleaning the device. hen removing any of the strainers 13 or 15 the handle 20 can be bent towards the wall of the basin so that it will be entirely housed in the groove 11 and form no obstruction to the removal of the strainer.

In Figures 7 and 8 are shown a view of a modified form of the coarse strainer. Numeral 22 designates the floor of the strainer, 23 the coarse holes therein and 2a the cylindrical wall member. The bottom of the wall member is provided with an inwardly bent flange 25 which is adapted to rest on the lower strainer 13. Extending from the cylindrical side wall are a pair of ears 26 which fit into the longitudinal grooves 11. V

The modified form of the invention shown in Figure 2 is practically the same as that shown in Figure 1 with the exception that the outer casing 27 is longer than the easing 2 and the top flange 28 of the casing is not bolted to the sink but rests on upstanding circular boss 29 of the drain 30. Numeral 31 represents an inner-basin which is the same in construction as the basin 9 excepting that it is longer to match the outer casing 27. At. the top of the basin 31 is a flange 32 resting on the flange 28 of the outer casing. Numerals 33 and 34 represent the longitudinal grooves which correspond to the grooves 11 and 12 of the casing shown in Figure 1.

This device can be attached to any existing sink, soft drink dispensing apparatus or other similar form of drains without any material alteration of the existing parts. The form of the invention shown in Figure 1 is mainly used for household sinks. The strainer 15 having .the comparatively coarse holes is adapted to catch the coarse refuse, the lower strainer 13havin finer holes will catch the fine particles of waste, while the auxiliary strainer 17 will catch the finest residue. With this construction an interrupted flow of .the drain water will he had without causing the plumbing line to be clogged up. The inner-basin 9 can be bodily removed by the aid of the handle 20 when it is desired to clean same. Also the strainers 13 and 15 can be removed or replaced when necessary. A supply of strainers of various size holes can be had in stock and any particular kind can be used to suit conditions.

The auxiliary strainer 17 is purposely made with an upwardly bent rim or fiange so that when it is removed for cleaning the particles of waste will not fall off. AJS previously stated the rim orfiange tapers to. suit the taper of .the'tapered portion 7 of the outer casing and is self seating.

The modified form illustrated in Figure 2 is 'mainly adapted for use with soda water dispensing apparatuses. The device is purposely made longer to accommodate the waste peculiar to this kindofbusiness such as straws, orange peelings,-etc. As previously mentioned, in principle this form of the modification is the same as thatshown in Figure 1.

It will thus be seen that I have provided an efficient, simple, and economical method of separating the solid matter from cleaning water before it reaches the sewers. The interior of the device can be bodily removed and cleaned and be kept in a sanitary and healthful condition.

Having described my invention, I claim;

1. In a device of the class described, the combination of an outer casing a basin in said casing, two pairs of longitudinal grooves in said casing, one pair of said grooves extending the full length of said casing while the other pair of grooves ending some distance from the bottom of said casing, a strainer of coarse mesh having outwardly extending ears housed and supported at the bottom .of said second mentioned grooves, and another strainer of fine mesh having outwardly extending ears housed and supported at the bottom of the first mentioned grooves;

2. In a device .of .the class described, the combination of an outer casing, a basin in said casing, two pairs of longitudinal grooves in said casing, one pairfof said grooves extending the full length of said casing while the other pair of grooves ending some distance from the bottom of said casing, a strainer of coarse mesh having outwardly extending .ears housed and supported at the bottom of said second mentioned grooves, another strainer of fine mesh having outwardly: extending ears housed and supported atthezbottom ofthe first mentioned grooves, and a resilient handle in one of said grooves.

3. In a device of the class described, the combination of an outer casing, abasin in said casing, two .pairs of longitudinal grooves in said casing one pair of said grooves extending the full length of said casing while the other pair of grooves ending some distance from the bottom of said casing, a strainer of coarse mesh having outwardly extending ears housed and supported at the .bottom of said second mentioned grooves, another strainer of fine mesh having outwardly extending ears housed and supported at the bottom r of the first mentioned grooves, a flange at the top of said outer casing, and a flange at the top of said basin resting on said first mentioned flange.

In testimony whereofI afiix my signa ture. I
